BED-BOTTOM FABRIC.

Specification of Letters Patent.

Patented March 9, 1909.

v Application filed December 3, 1908. Sfiia) No. 5,877.

Bo it known that l, FRANK W. lilxxnr, a

citizen of the United States, and a resident of hua igo, in the county of Cook and State of liilnnis, have invented certs-in new and us lul lmpi'OYcluOlllS in Bed-Bottom l.'ab-.

. r-irs, c! which the following is n specification.

The invention relates to wire fabrics for lllu bottoms of beds, couches and the like,und more particularly to that tvpe of fabric coniprisrnglongitudinal strands that are formed of bent wire links or units connected and to end, the separate longitudinal strands of the lain-u: being connected by cross links which {Ls-.lfit in supporting themattress upon the v ment, in which the connections between the longitudinal links will properly distribute and resist the tension strains upon the iongitudinal strands and which c-nnect-ions are of such. construction as to permit the ready assembling of the links, preferably by the machine in which they are f'jornlod.

A further object of the invention is to provide a connection bebween the longitudinal links and between the longitudinal and cross links of such a nature that, while the links may be readily assembled, the engagement of the cross links with t-he' longitudinal links will preventthe disengagementof the longitudinal links and the connections between the latter will hold the cross links iigainst dis lacenient.

he invention consists in the features of improvement hereinafter set forth, illustrated in the accompanving drawings and more particularly pointed out in the-appended claims.

In the drawings, Figure 1 is a? plan View of ortion of the improved fabric. 'a ngitudmal section on lined-2 of a F '2 is Fig. 3 is an enlarged detail view of the joints between the longitudinal links and between the latter and the moss one of.

The frame of the bed-bottom may be of usual form. In the drawings,-one of the end bars 11 snd'one of the longitudinal bars 10 of the frame are shown. These bars are preferably anglc-irons,--as indicated, and are suitaLly connected by bolts 12. The upstanding flange of the end bar 11 is, as usual,

provided with :1. series of openings 13 which receive the outer ends of the helical springs 14. The longitudinal strands of the fabric are connected to the inner ends. of these helical springs, each longitudinal strand extending from a spring connected to one end of the bed-bottom frame to a spring connected to the other end.

It sill be understood, however, that othe" means may be employed for mounting the improved fabric in the bed bottom frame.

The im )roved fabric ismade upoi' anuni'oer oi aralle ,iongitudinal strands, each of which nected end to end together with the cross links Each of the longitudinal is made from a single length of wire that is doubled or bent straight tension members 1.5 wide are bent at their ends to form terminal eyes 16 at the open end of the link. These eyes are ref era bly down-turned and arranged in a p one the fabric.' The contra port-ion 'of the length of wire from which the link is made, is bent to form an anchor-shaped head or eye tions of the anchor-shaped head or eye, in-

17, preferably lie in. .ue same horizontal plane and in the same plane with the two tension members 15 olthe link. The douof each link are arranged to project laterally through the terminal eyes at the open end of the next'adjucentlink, theterminal eyes being sulliciently larger than the anchorthe commuted longitudinal links. The adjacuntportions of the anchor-arms l7 and of the tension members 15 are shaped to form V-shaped seats 18 for the terminal eyes 16 of the next link, said seats be'mg closely a'djacent the tension members '15, so that the two tension members of each link will be substantially in line with the tension mem- 17 at the closed end of the link. All por-- arms to form .a flexible hinge joint between bars of the other links in the same longituis orrned of a number of similar links conwhich flexibly unite the adjacent strands. 1

centrally to form two substantiall parallel,

substantially at right anglles to theplane of i I cluding the laterally pro'ecting anchor arms ble wire anchor-arms 17" at the closed end rlinal strand. The longitudinal strands are Joli.

made up by simply spreading theopen ends of each link apart, as shown in Fig. 3, and:

. projecting the anchor-arms of thenext ad'- lalrient link through the terminal eyes 16.

e helical spring 14 at one endof each ion. gitudinal strand 1;; eizga ed with the two ternnnal eyes oi one end dink and the helical spring at the other end of the longitudinal a right angles thereto and engage the project-- ing anchor-arms 17 of the longitudinal links. These cross links are provided with bent end portions 20 which are hooked into the outer ends of the anchor arms. The separate longitudinal strands of the fabric are'first made up and are then connected by the cross links 19, the hooks 20' thereof extending through the anchor arms 17 outside of the terminal eyes 16. The eculiar man ner of connecting the longitudlnal and cross links prevents the displacement of the separate members of the fabric, sincethe bent end portions or hooks 20 of the cross links are of sufiicient size to reventthe disengagement of the tcrmina eyes 16. from. the

anchor arms 17. At the same time, the terminal eyes through which the anchor-arms project, prevent the displacement of the cross-links 19. Moreover, .since both terminal eyes of each longitudinal link project over the double wires of the anchor arms of the nest adj acent link, a very strong, though flexible, joint is formed between the separate links of the longitudinal strands which bear the greater amount of strain imposed upon the fabric. By reason of the fact that it is not necessary to open the terminal eyes in order, to connect up the longitudinal links, these strands can be readily and cheaply manufactured, since it is possible to bend them to form and connect them up in a single machine. I

I claim as my invcnt-ion':'

1. A bed-bottom fabric comprising a number of longitudinal, parallel strands formed of bent-wire links, each of said'links consisting of a doubled wire having terminal eycsat the open end of the link and ahchor arms at the closed end thereof that project laterally through the terminaleyes of the 3 next link, and cross-links engaaglilngi the projecting anchor arms of later y adjacent strands, substantially as described.

' .2. .A bed-bottom fabrieeomprising a num- -ber of longitudinal, parallel strands formed of bent wire links, each of said links consisting of a doubled wire paving terminal eyes at the 0 en end of the ink and anchor-arms at the c osed end thereof, the double wires ofwhich arms project laterally through the terminal eyes of the next link, and cross links having bent end portions hooked into the projecting arms of laterally adjacent strands, substantially as described.
